in the Italian Collection, of which ahout 1500 are skins and 

 1900 are set up, besides some 800 that are exotic. The series 

 of colour-variations — albinisms and other kinds — is very rich. 

 The skins are excellently made, carefully arranged, and fully 

 labelled. Herr Vallon gives a long list of the more remark- 

 able specimens, amongst which, we notice^ are nine examples 

 of Buteo desertorum and three of B. ferooc, one of Falco island- 

 icKS from Venetia, also specimens of Dendrocopus lUfordi, 

 Turdus fuscaius, Budytes citreolus, Emberiza aureola, E. 

 rustica, and E. pusilla, with many other Italian rarities. The 

 Count has, moreover, a consideral)le series of hybrids.

From the eighteenth report on the birds taken and observed 

 at the Danish Lighthouses (see Ibis, 1901, p. 150) we learn that 

 700 specimens were received in the year 1900 at the Zoolo- 

 gical Museum, Copenhagen, from 33 lighthouses. They are 

 referred to 53 species. An example of the slender-billed 

 form of theNntcracker [Nucifraga caryocatactesleptorhynchus) 

 was taken at the Hestehoved Station ou Oct. 30th. 



The total number of species as yet registered in these lists 

 is 144.

We have received the following letters since our last 

 issue . — 



Sirs, — Amongst the many interesting spring displays of 

 the Anatidce, that of the male Baer's Duck, which \ have 

 studied in the specimens living in the Gardens of the 

 Zoological Society of London, is somewhat remarkable. He 

 commences to " draw " about the same time as the Scaup 

 Duck, to which the species is evidently closely allied, and 

 as regards his nuptial courtship is similar in many respects 

 to that bird.
